"How pleased am I? So pleased that I'm revealing the working title for episode nine: 'Miller's Crossing.' I like it. We'll see if it sticks."(Executive producer Joseph Mallozzi, in a post at his blog)

Based on the title of this episode, it will likely see the return of actress Kate Hewlett as McKay's sister, Jeannie Miller. Jeannie first appeared a year earlier, in Season Three's "McKay and Mrs. Miller." She is a brilliant scientist who is living on Earth as a full-time wife and mother. (Confirmation is still pending.)
